SPINDLE FOR LOOM-SHUTTLES.

SPECIFICATION forming part of Letters Patent N0. 273,463, dated March 6,1883.

Application filed August 5, 1882.

To all whom it may concern:

Be it known that 1, WILLIAM T. OGGES- HALL, a citizen of the UnitedStates, and a resident of Lowell, in the county of Middlesex and Stateof Massachusetts, have invented anew and valuable Improvement inSpindles for Loom-Shuttles; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being bad to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 is a view of my improved spindle in section. Fig. 2 is aperspective view of the spring which is attached to and forms a part ofthe spindle, and Fig. 3 is a plan view of the under side of the spindle.

This invention has relation to spindles for loom-shuttles; and itconsists in the construction and novel arrangement, in a spindle.grooved longitudinally, of a spring fastened by its rear portion in therear end of said groove, rising at its upper edge above said groove, andprovided with a rounded projection above said groove at its point; inslotting the bottom of the groove in the spindle under the point portiononly of the spring, and providing said spring with an under extensionprojecting through said slotted portion, all as hereinafter set forthand claimed.

In the accompanying drawings, ades'ignates the spindle of aloom-shuttle, having a longitudinal vertical groove, 1), made in itsupper portion.

0 represents a flat spring, which is inserted edgewise in the groove b,so that it extends longitudinally therein, its upper edge projectingsomewhat above the groove. This .spring is rigidly secured, at its heelend 01, in

. the rear end of the groove by the two pins 0,

or by any common fastening device, and that portion of the spring whichis in front ofthe rigidly-fastened heel is raised somewhat above thebottom of the groove b. The upper or exposed edge of the spring may beserrated or notched; but this is not essential. At the free end of thespring is a rounded projection, g, which allows'the thread or filling topass over it without breaking. This rounded (No modeL).

projection rises out of the slot at the end of the spring, as shown inthe drawings. The tension of the spring 0 is upward and when the cop isput on it receives constant upward pressure from the spring, saidpressure increasing toward the free end of the spring,

and being greatest at or near its extremity. As'the thread unwinds,lessening the amount on the spindle, the tendency of the spring, fromits elasticity, is to gradually and evenly rise, presenting to thethread or cop a constantly-ascending edge, and thus acting effectuallyto prevent the slipping and consequent breaking of the cop.

In order to give greater depth of spring in the point portion, it isadvisable in some spin-. dlesvto slot the base of the groove 1) underthis part of the spring for a short distance, not greater than twoinches, and to form the spring with an under extension or under bearsigned to aid the under pressure of the spring in preventing thebreaking of the cop.

This spindle is designed to serve several important purposes. ItwilIprevent the cop from slipping and breaking, it will obviate theeffect of the concussions that occur when the shuttle strikes theloom-pickers, and it will prevent the thread from breaking at the cop asit unwinds therefrom. The spring may be fastened nearer the pointportion if a stiffer or stronger tension is required.

Having described this invention, what I claim, and desire to secure byLetters Patent,

1s- 1. A spindle longitudinally grooved at b in its upper portion, andhaving the spring 0 rigidly fastened by its rear portion in the groove,rising at its upper edge above said groove, and provided with the raised'rounded projection g at its free end or point, substantially asspecified.

2. A spindle formed with a longitudinal groove, 12, in its upper portionand partially IOU slotted through the bottom of said groove, I hereuntosubscribed my name in the presence near the point end, and having thespring 0 of two witnesses. rigidly fastened in said groove, with itsholding upper edge extended out of the groove WILLIAM COGGESHALL' 5 andits lower extension, is, adapted to project Witnesses:

through the slot, substantially as specified. JOHN I. COGGESHALL,

In testimony that I claim the above I have HENRY W. FOSTER.
